One thing we all have to remember: Every time we go out bowhunting we take the chance of wounding an animal, thats just the nature of the game.. no matter how much practice no matter how good a shot we are no matter how much overall preperation we take, theres still always that chance, what we have to learn is to do the best we can with every situation we get into and after that, what happens, well thats just the way it is, we have to move on knowing we did our best at everything, learn from that and go right back out again.... Thats just the chances we take....So dont get to down on yourself, your human and we all make mistakes...The most important part is you did all you could do, and you have learned from it.....
Good luck with your next hunt....
